SWITCH-STAND.

Speecaton of Letters Patent.

PatentedSept. 25, 1906.

To ./LZ, whom; it may concern:

Be it known that we, AUGUST Coirrs, residing at Wyricote, and WARNER B. COOKE, residing at Jenkintown, Pennsylvania, citizens of the United States, have invented certain Improvements in Switch-Stands, of which the following is a specification.

The object of our invention is to construct a simple and effective switch-stand which will lock a switch-rail in either the open or closed position and in which the connection with the switch-rail is made directly on the banner or target shaft.

In the accompanying drawings, Figure 1 is a perspective view of our improved switchstand with the cap removed. F ig. 2 is a plan view, partly in section, with the cap removed. lFig. .3 is a side view. Fig. 4 is a sectional view on the line 4 4, Fig. 2. Fig. 5 is a detail perspective view showing the operating-lever in the mid-position to more clearly illustrate the connection between the operating-lever and the switch-lever or targetshaft. Fig. 6 is a` detached perspective view of the connectingflink, and Fig. 7 is a modified forni of link.

A is the base ofthe stand having feet c, which rest upon the ties C C in the present instance, `so as to provide va clear space 0e-.l` tween the ties for the switch-rod and the proj ecting portion ofthe switch-lever.

A is a cap fitting upon the base A and inclosin@r the connecting mechanism. At one for the trunnion b of the operating-lever The bearing- Icap a2 forms part of the cap A', as clearly illustrated in Fig. 3. e On the opposite end of the trunnion b is an arm b', bent at the angle shown, and this arm is perforated at b2.

D is a vertical switch-lever shaft which' passes through the stand, having atits lower end an arm d and carrying at its upper end a target orbanner D. In the present instance the upper end of the shaft is squared, as shown in Fi'g. 1, and the target is secured to one side of the shaft by bolts or other fastenings. A collar d rests upon the cap A and is fixed to the shaft by the confining-screw d2, so as to hold the shaft D in the proper vertical position.

The shaft D is slotted at d3 for the reception of a iink E, Fig. 6.y A pivot-pin e passes through the heel of the link and through the shaft D, so that the link will freely swing in the slot of the shaft, but will prevent the shaft turning independently of the arm. The

outer end o the link is formed iiitoa pin e', which ts in the opening bzin the arm b of the operating-lever. Thus when the operating-lever is in the horizontal position, as shown' in Figs. 1 and 2, oneither side the link E, bearing against arm b and trunnion b at dead-center, locks the switch-lever shaft against rotary motion by any other means but the operation of the operating-lever. By throwing the operating-lever through a half-circle from one horizontal position into the other the switch-lever shaft D is turned through one-quarter circle by the link E, bearing against t-he sides of the slot d3, swing,- ing at`the saine time on the center e and the rounded .end e', moving in the opening b2 of arm I). Thus the switch-rail is moved and the target turned to indicate the position of the switch.

fis an eyebolt secured to the arm d of the switch-lever. A switch-rod F is connected to this eyebolt by a pinf. A Y

B is the usual form of operating lever and may or may not be provided with kthe weight B. p

In Fig. 7 we have illustrated the link E having a forked end which spans the targetshaft, dispensing with the slot in said shaft.

I I are the usual stops or catches for the operatin -lever, preferablyv rovided with the shou der i', so that when t e switch-lever is thrown into one position or the other it may rest upon the shouldersof a stop. The holls 'i are intended for the insertion of a padloc It will be seen by the above ldescription that the stand is made of very few parts, and the connection is so formed between the vertical switch-lever shaft and the operating-le-- ver that it will be impossible to accidentally shift the switch by any other means than the operating-lever, and yet the parts are so arranged that the operating-lever can he readily swung from one position to the' other. The operatin lever is moved through one-half circle. Y hus it is locked on dead-centers in either position, while the switch and targetshaft is moved through one-quarter circle.

Thus the target can assume its two positions of danger and saiety. Furthermore, as the target or banner is directly secured to the shaft of the switch-lever it is imposible to shift the switch-lever Without turning the target or banner.

W e claim The combination in a switch-stand oi a easing, alvertioal shaft having its bearings in the easingI an operating-lever having a trunnion mounted also in the easing arranged at right angles to the vertical shaft, an arno on said trunnion, a linli pivoted to the said vertical shait and Coupled to arrn oi the operating-leverJ a target Carried bythe upper end oi the vertical shait a oranlz at the lower end of the vertical shaft below the easing, a switeh-rod eoupled to the eranla, substantially as described.

2. The eoinbination in a switch-stand oi a base, a cap mounted on the base, and inelosying the operating mechanism, a vertical sha-ft having its bearings in the base and in the cap, an arm on the lower end ofthe shaft under the base, a bolt seoured to the arm, a switchrod connected to the bolt, an-operating-lever having a trunnion mounted in a bearing formed partly in the base and partly-inthe cap, an arm-on said trunnion, anda link piv oted to the vertical shaft and coupled to the larm of the operating-lever, said arm and link being mounted Within the easing formed by the base and'cap, substantially as described.

3. The combination in a switch-stand of a base7 a vertical switch shaft extending through the base, an arm on the shaft under the base, a bolt secure-dto the arm, and a switch-rod coupled to the bolt, a tar et earried by the upper end of the vertical s aft, an operating-lever havin a trur'inion arranged at right angles to t e vertical shaft and mounted in a bearing in the base7 an arm on the trunnion bent and perforated at its outer end, a link pivotedto the vertical-shaft and. having a rounded end extending into the perforation of the arm, the parts being so ar' ranged that the switch-shaft will be looked eaneaa against rotation When the operating-lever is in either oi its two extreme positions, substantially as deswibed. v

e. T he Combination of a base7 aeap mounted on the base, a vertical' shaft extending through the base and rough the cap, aeollar resting on the cap and seoured to the shaft holding the shaft in the roper vertical position7 an arni on the end oi the shaft below the base, asWitoh-rod oonneoted to the arm, a target secured to the upper end oi the shaft an operating-letfer having a horizontally-arranged trunnion mounted in a bearing in the base the operating-lever being mounted on the outside oi the base, an arm on the trnnnion bent at its upper end and perforated, and a link pivoted to the vertical shaft, and having a portion extending into the opening in the arm whereby the vertical shaft will be loeled against rotation when the operating-lever is in either oi its two extreme positions, substantially as deseribed.

rEhe combination in a base, a eap mounted on the base, a vertical shait extending through the nap and the base, atarget secured to the upper end or the shaft, a switchlever connected to the lower end of the shaft below the base, an operating-lever having a horizontal trunnion, an arm on the trnnnion having a perforation at its outer end, the vertical shaft being secured, a link E in the form of a plate having a reduced portion in the ormof a pin, the plate'bein pivotally mounted in the slot in the shaft, tie reduced .Portion of thelink'extending into the opening in the arm of the operating-lever, the oap inelosing the linkin the arno, substantially as described.

In testimony whereof We have signed our names to this speeiiioation in the presence of ltwo subscribing Witnesses.
